Buy DSIP Peptide in Australia
Buy DSIP in Australia from Macropus Peptides in three lyophilised strengths: 2mg, 5mg and 10mg. DSIP, delta sleep-inducing peptide, is a nine amino acid neuropeptide first isolated from rabbit blood and reported in 1977, and it remains a research compound whose gene and receptor have never been identified. Laboratories use it in EEG, neuroendocrine and stress-axis studies in animal models. The 10mg vial is priced and can be ordered now, while the 2mg and 5mg vials are quoted on request. Every sealed vial carries compound, strength, lot number and storage temperature, and a certificate of analysis is available for each lot. Add bacteriostatic water for reconstitution and your order ships from Australia to any address in the country. DSIP for sale to adults for in-vitro laboratory research only, not for human or veterinary use.

Buy DSIP Australia: 2mg, 5mg and 10mg Vials
Macropus Peptides supplies DSIP to Australian laboratories as freeze-dried powder in three strengths, 2mg, 5mg and 10mg. The 10mg vial is priced and ready to ship; the two smaller strengths are quoted on request. All three are filled from one synthesis and released by lot, so switching strength changes only the amount of peptide in the glass.
What is DSIP peptide
DSIP abbreviates delta sleep-inducing peptide, a label that records how it was found rather than a settled function. It is a linear chain of nine amino acids, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, with no disulfide bridge or unusual residues, which makes it one of the simplest neuropeptides in research use. It was isolated in Switzerland from the cerebral venous blood of rabbits during electrically evoked slow-wave EEG activity, and characterised in PNAS in 1977. Nearly fifty years later, neither a gene coding for it nor a dedicated receptor has been confirmed, and it has no approved use anywhere.
How the DSIP peptide works in research
Because no receptor is known, the nonapeptide is studied by what it does in a model rather than by where it binds. Early work recorded EEG delta activity in rabbits and other animals after administration. Later studies turned to the neuroendocrine system, measuring corticotropin and other pituitary hormones, and to stress responses. Immunoreactivity resembling it has been reported in the hypothalamus, pituitary, peripheral organs and plasma. One line of work found that antibodies raised against it also recognise a separate protein, the glucocorticoid-induced leucine zipper, which shares an epitope but is not its precursor. Findings differ between models and laboratories, and that uncertainty is exactly why the peptide is still ordered as an investigational probe.
DSIP research: what the studies show
The record begins with the 1977 PNAS paper describing isolation, amino acid sequence and EEG activity of the peptide in rabbits. Neuroscience and Biobehavioral Reviews published a review in 1984 covering its chemistry, tissue distribution and the physiological actions reported up to then. In 2006 the Journal of Neurochemistry reassessed the field under the title of a still unresolved riddle, setting out the missing gene, the missing receptor and the conflicting results. The literature is mostly animal work and short reviews, with few recent controlled studies. For each paper's model and measured endpoints, open the DSIP research studies library.
DSIP peptide vial specifications
| Specification | Detail |
|---|---|
| Compound | DSIP |
| Amount | 10 mg |
| Form | Lyophilised powder |
| Category | Longevity and cognitive |
| Storage | -20 °C, protect from light |
Each vial contains the nonapeptide as a fluffy white lyophilised cake, molecular weight roughly 849 g/mol, sealed with a stopper and crimp cap. The label gives compound, strength in milligrams, lot code and a frozen storage temperature. The tryptophan at the start of the chain is sensitive to light, so the vial should stay in its box in the freezer until use. Your certificate of analysis is issued against that lot.
DSIP peptide price and cost in Australia
| Strength | Price | Price per mg |
|---|---|---|
| DSIP 2mg | Price to confirm | - |
| DSIP 5mg | Price to confirm | - |
| DSIP 10mg | $109.99 | $11.00 per mg |
The 10mg fill is the priced strength and can be bought online now. The 2mg and 5mg fills are costed per enquiry while their list prices are set. Across our catalogue, cost per milligram falls as vial size rises, so the 10mg vial is the economical choice for any study that will use more than one small vial.
DSIP 10mg: where to buy in Australia
Buyers searching for this peptide mostly want the 10mg fill, and it alone carries a list price. It holds enough to take an EEG, hormone or cell series from pilot to replicates on one lot. A 2 mL addition of bacteriostatic water leaves the nonapeptide at 5 mg/mL; a 5 mL addition leaves it at 2 mg/mL.
DSIP 5mg: mid-size vial on quote
Half the larger vial, for a defined study that will not use 10mg within the stability window of a mixed solution. Diluted with 2.5 mL, this fill lands on 2 mg/mL, matching the 10mg vial taken up in 5 mL, so pipetting plans carry across.
DSIP 2mg: pilot vial on quote
The smallest fill, for method scouting and single assays where leftover solution would go to waste. A millilitre of diluent makes this pilot vial a 2 mg/mL stock. Ask for a quote before scheduling work around this size.

DSIP reconstitution and peptide calculator: water for each fill
Let the diluent trickle down the glass, then swirl rather than shake. Concentration is milligrams over millilitres:
- 10mg plus 1 mL: 10 mg/mL
- 10mg plus 2 mL: 5 mg/mL
- 10mg plus 4 mL: 2.5 mg/mL
- 5mg plus 1 mL: 5 mg/mL
- 5mg plus 2 mL: 2.5 mg/mL
- 2mg plus 1 mL: 2 mg/mL
For in-between volumes, the DSIP peptide calculator on the listing gives the answer in mg/mL and mcg/mL. Bacteriostatic water 10mL ships in the same parcel, and more diluents are in lab supplies.
Is DSIP available in Australia
It is available as a research chemical and nothing more. Australian regulators have never listed the nonapeptide on the ARTG or approved it, and may not be given to people or animals, which is why our release is limited to in-vitro study. The Poisons Standard governs scheduling and is revised periodically, so confirm its current wording for your laboratory before ordering.
DSIP for sale Australia wide
Laboratories in every capital and regional centre, from Townsville to Launceston, receive their vials by tracked post. Neuropeptide groups commonly combine this vial with Selank, Epitalon or the DSIP starter kit, and our wider longevity and cognitive range sits beside it.
